Yes, exactly. The logic in two successive if checks of "(update_type !=
UPDATE_TYPE_FAST) " is incorrect still.
Possibly we can update code by dropping one if check as below. Anyway, this
needs confirm from display team @Lee, Alvin @Lei, Jun.
if (update_type != UPDATE_TYPE_FAST) {
dc->hwss.post_unlock_program_front_end(dc, context);
if (dc->hwss.commit_subvp_config)
dc->hwss.commit_subvp_config(dc, context);
}

Subject: Re: [PATCH] drm/display: guard if clause
Well please adjust the subject line, that should read something like
"drm/amd/display:..." or "drm/amdgpu:...".

That looks like a step into the right directly, but please re-read the code:
if (update_type != UPDATE_TYPE_FAST) {
....
if (update_type != UPDATE_TYPE_FAST)
....
}
That's certainly still not correct.
